EXHAUST-MOTOR.

Specification of Letters'Patent.

Application filed June 26, 1912.

Patented Dec. 24;, 1912. Serial No. 706.029.

To all 'whom 'it mag/ concern Be it known that I, CAuL F. ilion, acitizen of the United States7 residingY at Madison, in the count)y ofDane and State of lVisconsin, have invented certain new and usefulImprovements in llxhaust-"Uotors, of which the following is aspecification.

My invention relates to an improvement in exhaust motors and the objectis to sulI stitute a motor for the fly wheel of an eu-l gine and to usethe exhaust gases from the engine cylinders for operatliner the motor.iVhiie the motor performs all of the funetions of a fly wheel. itsobject is to assist' in carrying` the cranks over the dead center andthis is accomplished by the impulse imparted to the 1notor-lrv theexhaust earl. In this manner the danger of tripping.;r the engine isovercome because the motor will receive the exhaust from the cylinderand the pressure of the gras will be sutlicieut` to carry the cranksover against compresa-ion as the high pressure exhaust, due to hie'hmean effective pressure, is increasing the turning' power of the motorand giving' power or aid in the turning' of the pistons against theco-n'ipression and therefore the more overload' that is placed upon thec vlinders, the higher the exhaust pressure and velocity and, theseactingv upon the rotor. which is at a low peripheral speed. the pull isincreased. l

The invention consists in certain novel features of construction andcombinations of parts which will be hereinafter more fully described.illustrated and claimed.

In the accompanying d-rawines-Figure l is a VView in elevation andpartly in see'- tion showing the manner of connecting' the invention toan engine and its relation thereto; Fig. 0 is a View .in sido elevationof a casing with the cover or one end plate remrn'ed; Fig. :i is avertical sectional View of the easing; Fig'. Il is a view in sideelevation of the rotor; Fig. 5 is a vertical seetional 'View ot' therotor; Fig. 6 is a sectional view taken at an angle of 90 degrees 'fromthe section shown in Fig. 3. Fig. 7 is a detail view of the crank shaftextension upon which the motor is mounted.

A represents the crank ease ot' a gas engine, and l is the crank shaftyto which cranks 2 are connected.

il represents the cylinders to which an exhaust pipe 3 is connected.

C represents the motor casing, and mount-l ed in the casing a rotor D.The rotor lf is mounted on au extension of the crank IshaftI 1 and isfastened to the shaft by a spline 4t.

Surrounding the .shaft 1 where it passes through the easing' is an airpacking 5 for preventing' the las leal-tine'. The shal't at this point'is provided with a left handed thread 6, which. due to its rotation.causes the gas to he fed back into the chamber or casing' when any gasdue to expansion should enter the threads.

The rotor D is provided on its outer surface with pockets T. Thesepockets are preferablvY arranged in series of three, there beine' first:1 large pocket. the next one beingT smaller and the last smaller thanthe .seeond. and the periphery of the rotor is made up in the formationof these pockets which receive the exhaust from cylinders of the gasengine through an outlet opening S in the easinglr C.

Formed between the hul) of the rotor and the periphery thereof are vanes9 and conneet ed to the rear edges of thc vanes are bla-.les 1t), l0. Anannular flange 11 prevents the ras from passing from the pockets T intoor against the blades l0. The blades l() are preferably curved andextend to the periphery ot' the rotor. Connected t0 the blades along:the rear side of the rotor is a disk 19. the disk bein;r secnrei)Yfastened to the blades so that it is carried with the blades duringtheir rotation and forms a means whereby the gas is caused to act uponthe blades .for Causing the rotor to rotate.

The casing' (l is provided with an exhaust discharge race t3 whichextends and is formed. in one end of the casing from the center andaround the hub of the rotor to the outer Vall thereof. The raee is inthe form of a conduit formed in the wall or end of the easinglr andbecomes larger as it runs inward from the peripher)r of the casinertoward the center and around the hub. The rotor receiving the exhaustgases from the gas engine through the opening S into the pockets 7 ofthe rotor said gases are discharged from the pockets 'of the rotor intothe conduitor racc and thence pass through the rotor between the vanes 9Where the gas will again actV upon these vanes and cause or produce arotary action and the gas will pass between these vanes und against theblades 10, traveling toward the periphery of the blades and imparting `apropelling action which assists in causing the rotor to rotate. The vgasis discharged from these blades into the conduit or chani 4. the gas tobe discharged against a `fan (not shown), the fan being the type used onmotors for cooling purposes. This opening can be closed if the fan isnot used or it is not desired to operate itby means of the opening.

With an apparatus of thischaracter the exhaust gases from an engine canbe conducted to the casing of the apparatus where the gases will enterthe buckets or pockets 7 of the rotor and the gas may cause the rotor tobe rotated and the gas escapes fromthe pockets through the conduit whichleads to the center of' the casing where the gas will pass throughthehub of the rotor acting upon vanes and blades carried by the rotorwhereby the gas will again act upon the rotor for causing it to rotate,and each limpulse stroke of a cylinder of the gas engine is followed byan impulse on the rotor by the exhausted gas acting upon it. After thegas has done its work on the rotor, it is carried 'zhrough the conduitvwhere it is exhausted lfrom the bucket Where it gains velocity byvirtue of its expansion. yThis velocity gives impulse to the vanes 9which are set at an angle to the rotor hub and after the gas has passedover the vanes it enters at 'the'base of the receding diverging blades'Where the remaining expansion drives the gas outward and the reactionassists in turning the rotor, and as there is no external pressure onthe back or open side.v the entire pressure is for ward and this helpsin turning the rotor. Thus the movement gained h v theiirst impulse andall subsequent work done. on the rotor due to expansion. creates powerwhich can be added directly to the power ot the cylinders. Furthermore,with this appara- "tus therewill be no exhaust detonation as the-gas isexpanded .during its entire course through the motor. lt is broken up bythc rotor and blended into a constant pressure in the exhaust receiver'.The contact of the gas with the motor easingr allows the casing toradiate oft' a certain amount ot the heat,

thus reducing the volume and pressure.

ln the inner wall of the casing and adjacent to the inlet opening 8 area plurality ot' pockets 17, the purpose of which is to change thedirection of the gases or vapors entering the casing and cause them tobe directed toward the pockets 7 of the rotor.

Having thus described my invention, what I claimas new and desire tosecure by Letters Patent is-- 1.111 an exhaust motor, the combinationwith a casing having an exhaust inlet, of a rotor rotatably mounted inthe casing having pockets formed in the periphery thereof adapted toreceive the exhaust gases as they are delivered to the casing Yforimparting a rotary movement'to the rotor, blades connected to the rotor,a conduit in which the exhaust gases are delivered after theyhave actedupon the rotor, and a passage formed in the rotor whereby the gases passfrom the conduit to the rotor and against the blades for impartingadditional power to the rotor.
